Lord Venkatesvara & Tirupati Notes

In Varaha Purana is described:

Sveta-Varaha manifest during the night of Brahma, the pralayakalpa, when the earth melted and sank to patalaloka. Visnu had been lying on a banyan leaf floating on the water in Maharloka as Vatapatra-sayi when He thought of re-creating by rescuing the earth. He fought with Hiranyaksa, slit his body in two with His tusks, the blood of the demon causing the water to turn red. Brought up earth on His tusk, stood up in the Janaloka like a stupendous mountain, placing one foot on Adisesa.

Then on request of Brahma and devas he fixed the earth as before, divided the sapta-sagaras (seven oceans) and sapta-lokas (seven worlds) as formerly. He next bade Brahma to create the Jagat (world) as before.

Wanting to reside on earth for some time and protect the inhabitants, He ordered Garuda to fetch the Kridacala (sacred hill) from Vaikuntha. Then He selected a spot for the hill.

300 miles long by 30 miles wide, the hill is shaped like Sesa.

Brahma etc. prayed to Him to please become peaceful and composed, and to rest on this hill and grant boons to all people unable to reach Him by dhyana-yoga or karma-yoga.

Since then He resides invisibly on the hill, amusing Himself with Laksmi beside rever beds, on torrent ridges and in the valleys of the Hill. Sometimes He appears to saintly persons. He will remain here to the end of Sveta-Varaha-Kalpa (the present kalpa) The Hill is also known as Sri Varaha Ksetra. "I like this Venkatadri more than Vaikuntha; here shall I rest with Sri and Bhumi, and be resolved to grant the prayers of men."

The hill will appear in Kali-yuga to be an ordinary rocky hill; at other times it manifests as a golden mountain, as a personification of knowledge and wisdom, as a heap of gems, or as be-jewelled Srinivasa Himself.
